AUSTIN, Texas — Everything about “This Is Us” makes people cry, even stories about the fans.

Milo Ventimiglia, who plays TV’s favorite dad, Jack Pearson, had the audience in tears at ATX TV Festival on Friday when he recalled his most memorable fan interaction.

“There was one gal that walked up to me [at the airport] and kind of quietly said to me, ‘I just wanted to thank you. My husband and I adopted a boy and my husband had a really hard time with him. We watch your show and we see the relationship between father and adopted son and I just want to thank you for your portrayal,'” the 39-year-old actor said.

He continued, “she pulls out the phone and shows me a photo of her son and husband, and I’m really trying to keep myself together.”

On the NBC show, Ventimiglia’s character and his wife, played by Mandy Moore, welcome twins and adopt a son on the same day who was abandoned at the hospital.

“The nicest thing that I’ve been able to experience is when this show and all its makings has managed to impact people in lives and it’s given them an opportunity to have a conversation,” he told the crowd, adding, “it sparked a trend of coming together and actually trying to relate and move forward as opposed to hold on to whatever’s been kicking our ass for years.”
